As Microsoft promised at Build earlier this month—and, geesh, that feels like months ago—it has open sourced the Xamarin SDK. Brad reports over on Petri:

The Xamarin SDK for Android, iOS and Mac, under the same MIT license used for the Mono project, have all been open sourced which means any developer can now contribute to the project. This newly released source code includes native API bindings for iOS, Android and Mac, the command-line tools necessary to build for these platforms, and Xamarin.Forms, Xamarin’s cross-platform UI framework.

MODE snap-and-swap watch bands feature a simple slide button so you can attach and detach your band in one click.

MODE bands are versatile—they come in four widths, fit most Android Wear watches, and work on mechanical watches too. This first collection comes in a rainbow of colors, and is available in leather and silicone, so you can easily go from the office to the gym to a night out.

This is just the beginning. We want Android Wear to give you as much choice as possible, so we’ll be sharing the MODE mechanism design and source with other brands to use to create their own snap-and-swap watch bands.

My confusion is this: In the pictures, you can see that the MODE bands connect to a rod that is on the watch. But my Moto 360 doesn’t have that rod; the rod is on the band parts. Maybe the MODE bands include the rod(s)? Hm.

Beyond that, just knowing which size to get is confusing. I obviously don’t “get” fashion.
